If I have a link ( http://www.iep.utm.edu/natlaw/#H4 ) I understand the the #14 is the part that takes me to a certain spot in the page. If I am designing the page, what code or attribute do I use to accomplish the marker that will allow the link to go right to that specific spot in the page?

You have two options. One is an empty anchor tag with a name attribute. The second is to take advantage of an existing tag and match the hash tag text to a matching id attribute.
